swift里 怎么把字典或者数组转json字符串

Answer 1

您好，很高兴为您解答，方法好下： +(NSString *)stringTOjson:(id)temps //把字典和数组转换成json字符串 { NSData* jsonData =[NSJSONSerialization dataWithJSONObject:temps options:NSJSONWritingPrettyPrinted error:nil]; NSString *strs=[[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding]; return strs; } 利用NSJSONSerialization序列化成NSData,再通过NSString 转成JSON字符串 func toJSONString(dict:NSDictionary!)->NSString{ var data = NSJSONSerialization.dataWithJSONObject(dict, options: NSJSONWritingOptions.PrettyPrinted, error: nil) var strJson=NSString(data: data, encoding: NSUTF8StringEncoding) return strJson }
